prostetiske

Prostetiske is the Danish term for prosthetic devices that replace missing body parts or restore lost function. In English, prosthetic refers to artificial limbs and other replacements designed to maintain mobility, dexterity, or appearance after amputation, congenital absence, or injury. Prostetiske devices encompass a range of technologies from simple cosmetic supports to advanced mechatronic systems.

Common types include external limb prostheses for the upper and lower extremities, cosmetic or functional facial prostheses (eyes, ears, nose), and dental prosthetics such as crowns and dentures. Internal prostheses, such as joint replacements and implanted devices, also fall under the broader category of prosthetics.

Typical components of external prostheses are a socket or interface to fit the residual limb, a pylon or shank to transmit forces, and a knee, ankle, or foot unit. Interfaces may include harnesses, suction, or silicone liners, while control can be body-powered, myoelectric, or microprocessor-guided.

Materials range from carbon fiber composites and lightweight polymers to medical-grade silicone for cosmetic coverings. Modern manufacturing leverages 3D printing, computer-aided design, and modular components to improve fit, function, and comfort.

The history of prosthetics spans ancient civilizations to present-day innovation. Early devices were simple tools and cosmetic shells. Advances in the 19th and 20th centuries, driven by military injuries, led to more durable limbs. The late 20th century introduced myoelectric control and modular components; recent decades have seen osseointegration, smart sensors, and powered prostheses.

Access and cost remain key issues, with outcomes depending on fitting, rehabilitation, and user training. Ethical considerations include autonomy, body image, and the potential for enhancement versus replacement. Research continues to improve control, sensation, and integration with the nervous system.
